This pair of hp’s sound good. Fit is difficult to deal with. Scrolling with the in line remote does not always work Properly. I know about battery charge and shake to shuffle. I still have concerns about reliability. I did discuss issues about function with sales rep David and at that time it seemed like the hp’s functioned properly, However within the last two days it has malfunctioned about 5 times. I did tell David that I would like to keep them. I do think that I have corrected all "operator headspace" errors. With this in mind please advise. Thanks, Randy
